本研究探讨了不同硬木特性对酶解的影响。采用13 C NMR定量分析、图像分析和纤维品质分析等方法对3种桉树等重要阔叶树种进行了综合表征。所有硬木的水解效率与木材化学组成和木质素特性相关。在控制酶解效率的关键木材组分中，木质素含量、酶在底物上的吸附以及预处理原料的S/G比被确定为最重要的。没有发现木材形态特征对预处理样品的酶转化有显着影响。
This study investigated the influence of various hardwood characteristics on enzymatic hydrolysis. Important hardwood species, including three Eucalyptus species, were comprehensively characterized using quantitative13C NMR, image analysis and fiber quality analysis. Hydrolysis efficiency from all the hardwoods was correlated to the wood chemical composition and lignin characteristics. Among the key wood components that control enzymatic hydrolysis efficiency, lignin content, enzyme adsorption on substrate and, the ratio of syringyl/guaiacyl (S/G) of the pretreated feedstock were identified as the most important. No wood morphological feature was found to have a significant influence on enzymatic conversion of the pretreated samples.
